The basics of counting, measurement and position detection
2.2 Basics of counting, measuring and position input (TM Count, TM PosInput, Compact CPU)
System environment for a Compact CPU
The Compact CPUs can be used in the following system environments:
Application scenarios
Central operation with a
S7-1500 Compact CPU
Parameter assignment options
In an S7-1500 system, you have two options for parameter assignment and control of
technology module functions:
● Configuration using the technology object and control using the associated instruction
Access to the control and feedback interface of the technology module takes place
through the technology object.
● Parameter setting via hardware configuration
The control and feedback interface of the technology module is accessed using direct
access to the I/O data.
